ECO401 Assignment No 01 Solution Fall 2019

ECO401 Assignment
TR= 100Q-1.5Q2
(a) Profit maximizing out put level at MC=MR
= 15
28.34 = Q
(b) Total profit Tπ
Tπ= TR – TC
= 100Q – 1.5Q2 – (30 + 15Q )
= 100Q – 1.5Q2 – 30 – 15Q
= 85Q – 1.5Q2 – 30
By putting value of Q
= 85(28.34) – 1.5(28.34)2 – 30
= 2408.9 -1.5(803.1556) – 30
= 2408.9 – 1204.7 -30
Tπ = 1174.2
(i) Calculating average revenue (AR)
= (100Q – 1.5Q2)/ Q
= 100 – 1.5Q
= 100 – 1.5( 28.34)
= 100 – 42.51
= 57.49
(ii) slope of AR function
Slope of AR = dAR/dQ
=d/dQ (AR)
= d/dQ (100 – 1.5Q)
= -1.5
